Newbie question, sorry if this sounds dumb. I'm using a GF1 with the 20mm and frequently use the "Direct AF Area" function to select a focus point that is outside of the center of the frame. Is there a quick/easy way to have the focus point snap back to the default position in the center of the frame? Is there a better way to be doing this? Should I be using AF Lock and recomposing? How does using AF lock differ from just keeping the shutter button depressed and re-composing? As you can imagine, reading the GF1 manual has not been especially helpful.
